Plant
Three sealed quench lines. Three tempering furnaces.
Parts are hardened and quenched inside a sealed atmosphere, washed, and moved to tempering on a logged clock. Here is what runs on the floor.

Sealed quench furnaces
Carburise, carbonitride or harden, then drop straight into the integral oil quench without exposing parts to air. Carbon potential is held by oxygen probe.
